I want to send some predefined reports via email using dbms job. For this, i am trying to use APEX_UTIL.GET_PRINT_DOCUMENT function signature 2 which returns a document as BLOB using pre-defined report query and pre-defined report layout. I have created a report layout(in rtf) and report query (with report in pdf format) in Apex Shared components. Query works fine (returns pdf report) when I check it using Test Report button in report query.
